I think it’s A not sure tho :|
        
             
        
        
        
All the angles of a triangle add up to 180 degrees. 
30+39+<4= 180
69+<4= 180
Subtract 69 on both sides. 
<4= 111 degrees
<1 and <4 are supplementary and adjacent. They equal 180 degrees as well.
111+<1= 180
<1= 69 degrees
I hope this helps!
